This main project involves the development of an electric powered formula racingcar. The part of this car that involved EBH was the battery handling to guarantee safe andquick battery exchanges during pit-stops.The solution became an entire battery module, hanging on the side of the car on two spearspointing out from the car. The batteries are exchanged by a specially designed trolley that isinserted under the battery module.

Predation på evertebrater under tidig vår i sjön Tåkern

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

Anorexia Nervosa - en fast identitet i en flytande modernitet? : En kvalitativ undersökning av individer som utvecklat anorexia

The aim of this study is to analyze how individuals experience their eating disorder, the focus being if anorexia may be perceived as a secure safe zone in the new modern world. The aim is to examine if individuals affected with anorexia nervosa understand the disorder as a solution to the modern worlds changes and the new individual freedom that it entails. This will be analyzed with the help of terms in Erich Fromms theories about escape mechanisms and Catarina Kinnvalls theories about the modern worlds ontological insecurity.The study is based on data collected from four informants of different ages and gender. The interviews were conducted through email and informants were chosen based on a strategic selection and snowball sampling. For the analysis of the empirical material Fromms escape mechanisms (authoritarianism, destructiveness and automaton conformity) and Kinnvalls theories of identity in the modern world have been used.The results of the analysis show that the eating disorder has a great significance for the individual construction and maintenance of identity and that the eating disorder becomes a safe zone to retreat to in a world of performance anxiety.

"The simple act of riding a bike" : Svenska och amerikanska kritikers reception av filmen Den Gröna Cykeln

Uppsatsens syfte är att granska sexton recensioner publicerade i svensk respektive amerikansk press gällande filmen Den Gröna Cykeln (Haifaa Al-Mansour, 2012). Undersökningen grundar i kritikernas syn på genus och jämställdhet samt kulturell och nationell identitet som filmen berör. Recensionerna analyseras och jämförs för att hitta skillnader och likheter i den svenska respektive amerikanska receptionen. Analysen visar att skillnaden mellan de två nationernas reception är uppdelade mellan de två fokusområdena, där de amerikanska kritikerna fokuserar på kulturell och nationell identitet och jämför filmens skildring av det saudiarabiska samhället med den amerikanska kulturen. De svenska kritikerna tycks generellt ha större fokus på filmens skildring av genus och jämställdhet till skillnad från amerikanerna..

Vad påverkar HIV i Sydafrika? : En teoretisk och empirisk analys av Sydafrikas provinser 2008

What affects Hiv in South Africa's different provinces? This thesis examines if education, unemployment rate, GDP per capita, and the literacy rate has any relationship with the Hiv prevalence. This is analyzed using theory and data in the form of a simple microeconomic model and an econometric regression analysis based on cross sectional data of the provinces of South Africa. The regression analysis shows that unemployment rate and education have significant effects of the Hiv prevalence in South Africa. The microeconomic model in the thesis indicates that when education is higher, individuals are more aware that the probability of being infected by Hiv is higher when the Hiv prevalence is high.

Indexeringskonsistens: En litteraturgenomgång och en undersökning i LIBRIS

The aim of this thesis is to investigate indexing consistency in LIBRIS, a Swedish national union catalogue, where searches can be carried out among almost five million titles. To calculate consistency, indexing terms of translations and indexing terms of documents in their original language have been compared. I have used a total of 100 such pairs in the study. There is a lot of different methods that can be used when consistency is calculated, in this study Hoopers and Rollings methods have been used since they are two of the most commonly methods used and also have the advantage of being fairly simple to use and understand. In the thesis, differences in consistency between indexing terms consisting of names and general indexing terms and differences in consistency between controlled indexing terms and uncontrolled indexing terms are also compared.

Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Småföretagsfördelar vid tillväxt

Growth of small businesses is vital to the Swedish economy, and many entrepreneurs want their enterprises to grow. However, the business climate of today is more changing than ever, and attributes becoming increasingly important for companies in order to deal with this are flexibility, speed, and adaptability: characteristics normally attributed to small enterprises. As a larger organization often is associated with more rigidity as a consequence of a higher degree of formalization, entrepreneurs are hesitant to seize growth opportunities, as they fear it will have negative impact on the aforementioned competitive advantages their enterprise possesses as a small business. This simple case study of a growing small enterprise investigates the effects of organizational growth on a small business' organizational structure and through its above mentioned advantages. The study finds that avoiding formalization while growing damages the competitiveness of the firm, and concludes that a degree of formalization is a necessity to maintain the flexibility, speed and adaptability in a growing small business..

Optimizing amount of straw for growing-finishing pigs : considering time spent in manipulative behaviour

In support to a decision to be made by the Swedish central competent authority on a minimal amount of straw for conventional growing-finishing pigs, a study using 168 pigs provided 7 different amounts of straw (20, 40, 60, 80, 100, 200 or 300 grams/pig/day) was performed. The straw was provided either once or four times per day. Detailed behaviour observations were made using focal animal sampling and continuous recording for one hour between 9 and 10 am and again between 3 and 4 pm. The data analysis is presented in three ways: broken stick model, polynomial trend line and logarithmic trend line. No method was suitable on its own but the use of all the methods simultaneously was found to portray the data in the best way.No significant differences were found when comparing pens provided with straw once or four times per day.
